Determinación de cristales en orina como predictor de riesgo litogénico

ABSTRACT Crystalluria, a marker of urinary supersaturation, depends on the concentration of salts and urinary pH. It mainly affects the kidney and lower urinary tract with significant acute or chronic repercussions. At present, renal lithiasis is the most frequent pathology associated with calcium stones, the majority mainly composed of calcium oxalate, and less frequently, calcium phosphate. Patients can undergo basic laboratory tests, with particular attention to evaluating urinary sediment. For this, a bibliographic review study was carried out based on 40 literary sources updated and recognized by the scientific community, in English and Spanish, found in databases such as PubMed, Scopus, academic Google, Lilacs, Embase, etc. to discuss urinary crystals considered as predictors of lithogenic risk. Excessive crystalluria and stone formation was found to depend on urinary and dietary factors, drug use, genetic background, medical conditions, and pregnancy. In addition, the prevalence of the different components of the stones in nephrolithiasis varies with age and gender, being the most frequent calcium oxalate in young adult men and adults, uric acid stones more recurrent in older adults, struvite and citrate in young women. Knowing the type of crystal is essential for the doctor since it guides the diagnosis, the optimal clinical or surgical therapy for each case, and recognizes the possible lithogenic risk factors according to the evidence of the stone compound found.
